I've created a song in Music Maker 2014 (if you want to hear it, there's the link: https://soundcloud.com/user-621585144/sea-cave) using almost only MIDIs composed by me, some instruments were built in. This post: https://www.magix.info/uk/forum/selling-music-created-in-music-maker-using-my-own-loops--1007531/ explained licensing topic really well, but in my song I've used one instrument, that doesn't support creating own melodies or rhythms - Atmos. This instrument just plays ambient sounds, no composing my own content.

I want to now if I can allow download of song containing Atmos' sounds on Creative Commons license. I'm not going to sell the song now, but if I want it, I'll buy required licenses. In meanwhile I want to have it as CC song for everyone to use it, even in Youtube videos with ads. Can I allow downloads?

Thanks for help in advance!
